Described leak source interface be positioned at sealing plate a depressed part of central position, the bottom of this depressed part is provided with through hole and is communicated with exhaust connection.Leak source interface and exhaust connection are weldingly connected.Valve links to each other by screw thread with outlet pipe with exhaust connection.
When pipe leakage was carried out leak stopping, described leak source interface was aimed at and is leaked breach, and the sealing plate bending closely encases pipeline and is welded on the pipeline.Described sealing plate the length of at least one side should be more than or equal to the girth of pipeline section.Described sealing plate thickness should meet the pipeline thickness calibration.
When leak stopping was carried out in leakage to the pipeline adpting flange, described leak source interface was aimed at leakage point, and the sealing plate bending closely encases flange and is welded on the flange.Described sealing plate thickness should meet the pipeline thickness calibration, described sealing plate material identical with the material of flange, described sealing plate size equate with the lateral area of flange.
Leak source interface of the present utility model makes pipe pressurized leakage-baffling device aim at leakage point easily, and can compensator or trimmer pressure.Owing to adopt pipe pressurized leakage-baffling device described in the utility model, when pipeline or flange connections leakage, need not close pipeline and carry out mending-leakage and repair, in addition, thisly emergently remedy that apparatus structure is simple, cost is low, easy construction, effectively controlling plumbing fixtures is leaked.
